    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • With reference to FIGS. 1-3, a device according to a preferred embodiment of the present invention comprises: a box 1, a sealant supply can 2, and a connection hose 4.
  • The box 1 includes a button 11 fixed on a top thereof, a coupling orifice 12 defined on a peripheral side thereof, and a body of the air compressor (not shown) accommodated in the box 1. The connection hose 4 includes a first segment 41 formed on a first end thereof, and the connection hose 4 includes a second segment 42 formed on a second end thereof and having a check connector 5 connected on the second segment 42. The sealant supply can 2 is connected on the coupling orifice 12, and the tire sealant supply can 2 includes an open segment 21 extending downward, a bottom fringe 22 extending upward, and a supply tube 23 configured to engage with the first segment 41 of the connection hose 4. The check connector 5 of the second segment 42 of the connection hose 4 is screwed with an air nozzle 9 of a tire 99, when feeding chemical sealant and inflating compressed airs to the tire 99 which is broken. After the box 1 is started by a vehicle power supply or other DC power supplies, the compressed airs of the air compressor force the chemical sealant of the sealant supply can 2 to flow into the tire 99 via the connection hose 4, thus repairing and inflating the tire 99. The tire 99 is any one of an automobile tire, a motorcycle tire, and a bicycle tire.
  • Referring to FIGS. 2-7, a check joint structure for a connection of the air nozzle of the tire and a connector of the connection hose of the air compressor is applied to avoid eruption of the chemical sealant, and the anti-spray joint structure comprises: the check connector 5 connected on the second segment 42 of the connection hose 4, the check connector 5 includes a fitting sleeve 6 (as shown in FIG. 4) formed in a cylinder shape, and the fitting sleeve 6 has a chamber 60 defined therein, a threaded orifice 61 formed in a first end thereof and having female threads, a through orifice 620 defined on a second end of the fitting sleeve 6, a projected shoulder 62 formed on an inner wall of the chamber 60 proximate to the through orifice 620, and a diameter of the projected shoulder 62 is more than a diameter of the through orifice 620, wherein the threaded orifice 61, the chamber 60, and the through orifice 620 are communicated with one another. A cylindrical base 7 (as shown in FIG. 5) includes a cylindrical room 70, a trench 71 formed on an outer wall of a first end of the cylindrical base 7, a stepped coupling segment 72 extending on an outer wall of a second end of the cylindrical base 7, and a conduit 73 defined in the stepped coupling segment 72 and communicating with the cylindrical room 70, wherein a diameter of the cylindrical room 70 is more than a diameter of the conduit 73, and the cylindrical base 7 further includes a first stepped portion 74 formed between the cylindrical room 70 and the conduit 73, a recessed section 75 formed proximate to the stepped coupling segment 72, wherein a diameter of the cylindrical base 7 is more than a diameter of the recessed section 75, and a second stepped portion 76 is defined between the cylindrical base 7 and the recessed section 75; a first seal ring 77 fitted on the trench 71 of the cylindrical base 7; a first spring 51 is received into the cylindrical room 70 of the cylindrical base 7 so that a first end of the first spring 51 abuts against the first stepped portion 74; a valve bolt 52 formed in a column shape and includes a first depressed section 521 formed on a first end of the valve bolt 52, a second depressed section 522 formed on a second end of the valve bolt 52; a contacting element 53 having a notch 530 defined in the contacting element 53, at least one cutout 531 defined on an outer wall of the contacting element 53, wherein the contacting element 53 is fitted into the first depressed section 521 of the valve bolt 52 by way of the notch 530; the second end of the valve bolt 52 is inserted through the cylindrical room 70 of the cylindrical base 7 and the conduit 73 of the stepped coupling segment 72 to extend out of the stepped coupling segment 72 of the cylindrical base 7, and the contacting element 53 abuts against a second end of the first spring 51, as shown in FIGS. 3 and 7; a first abutting loop 54 being fitted on the second depressed section 522 of the valve bolt 52 and fixed by a lock element 55, such that the first spring 51 pushes the valve bolt 52 so that first abutting loop 54 of the valve bolt 52 contacts with the stepped coupling segment 72 of the cylindrical base 7 and closes the conduit 73; the stepped coupling segment 72 of the cylindrical base 7 is put into the chamber 60 from the threaded orifice 61 of the fitting sleeve 6 via the through orifice 620, such that the projected shoulder 62 contacts with the second stepped portion 76 of the cylindrical base 7, the stepped coupling segment 72 of the cylindrical base 7 extends out of the fitting sleeve 6 to connect with the second segment 42 of the connection hose 4, and a fixing bushing 40 is configured to connect the connection hose 4 and the check connector 5, as illustrated in FIG. 3. The first spring 51 forces the first abutting loop 54 of the valve bolt 52 to contact with the stepped coupling segment 72 of the cylindrical base 7 and to close the conduit 73 of the stepped coupling segment 72.
  • Referring to FIG. 7, after the button 11 of the box 1 is turned on (as shown in FIG. 1), a pressure of the compressed airs of the air compressor forces the chemical sealant to flow, but the chemical sealant does not flow through the conduit 73 of the stepped coupling segment 72 because the first abutting loop 54 of the valve bolt 52 contacts with the stepped coupling segment 72 of the cylindrical base 7 tightly to stop the chemical sealant flowing through the conduit 73 of the stepped coupling segment 72, thus avoiding the eruption of the chemical sealant.
  • As shown in FIGS. 8 and 9, a valve core assembly 91 is accommodated in the air nozzle 9 of the tire 99, and the valve core assembly 91 includes a mounting 92, an arcuate stop shoulder 921 surrounding around a mouth of the mounting 92 and extending inward from an end of the mounting 92, and an aperture 922 defined in the mounting 92; a hollow receiving sleeve 93 having a retaining shoulder 931 formed on a first end of the hollow receiving sleeve 93, and a holder 932 formed on a second end of the hollow receiving sleeve 93; a central needle 94 formed in a column shape and having multiple spaced ribs 941 formed on the central needle 94; a second spring 95 fitted with the central needle 94 and a first end of the second spring 95 abutting against the multiple spaced ribs 941 of the central needle 94; the central needle 94 being received in the hollow receiving sleeve 93 from the first end of the hollow receiving sleeve 93 so that a second end of the second spring 95 contacts with the holder 932, and the second spring 95 is surrounded by the receiving hollow sleeve 93; a second abutting loop 96 fitted on a first end of the central needle 94; wherein after the hollow receiving sleeve 93 is connected with the mounting 92, the arcuate stop shoulder 921 of the mounting 92 engages with the retaining shoulder 931 of the hollow receiving sleeve 93, a second end of the central needle 94 extends out of the aperture 922 of the mounting 92, and the second spring 95 pushes the second abutting loop 96 of the central needle 94 to close the holder 932 of the hollow receiving sleeve 93.
  • As illustrated in FIGS. 1 and 8, when the threaded orifice 61 of the check connector 5 is screwed with the air nozzle 9 of the tire 99, the valve bolt 52 of the check connector 5 contacts with and urges the central needle 94 of the air nozzle 9 of the tire 99 to move so that the second abutting loop 96 of the central needle 94 removes from the holder 932 of the hollow receiving sleeve 93 (as shown in FIG. 9). When the threaded orifice 61 of the check connector 5 is screwed with the air nozzle 9 of the tire 99, the valve bolt 52 is urged by the central needle 94 of the air nozzle 9 to press the first spring 51 so that the first abutting loop 54 detaches from the second segment 72 of the cylindrical base 7, and the conduit 73 of the stepped coupling segment 72 is communicated, in the meantime, the chemical sealant is pushed by the compressed airs to flow into the tire 99 via the conduit 73 of the cylindrical base 7, the cylindrical room 70 of the cylindrical base 7, the at least one cutout 531 of the contacting element 53 of the valve bolt 52, the chamber 60 and the threaded orifice 61 of fitting sleeve 6, the aperture 922 of the mounting 92 of the air nozzle 9, the hollow receiving sleeve 93, and the holder 932 of the hollow receiving sleeve 93, thus feeding the chemical sealant and inflating the compressed airs to the tire 99.
  • Thereby, the check joint structure for the connection of the air nozzle of the tire and the connector of the connection hose of the air compressor is capable of avoiding the eruption of the chemical sealant in an incorrect operation.
